Question

Which is equivalent to sin^-1(.75)

Answer 1

Answer: 0.85 radians

Explanation:

We have the following trigonometric expression:

`sin^(-1)(0.75)=arcsin(0.75)`

The result of this calculation is:

`sin^(-1)(0.75)=48.59\°` where the angle is in degrees

If
`360\°=2\pi rad` then:

`48.59\°((2\pi rad)/(360\°)=0.848 rad \approx 0.85 rad`

Therefore the answer is 0.85 radians
